Abstract

PURPOSE:To prevent short circuit between a circumferential end section of a semiconductor substrate and a heat sink at the anode side by a method wherein the peripheral section of a main surface with a projecting electrode of the semiconductor substrate and one section of a flank continuing to the peripheral section thereof are coated with an electric insulating film. CONSTITUTION:With a double-heat sink-diode (DHD) type semiconductor base body 6, a P type region 2 is formed on a main surface of a substrate 1 consisting of an N type region, a projecting electrode (anode electrode) 3 is made up on the P type region as a drawing electrode, and a metallized electrode 4 is built up on the opposite flank of the main surface. An electric insulating film (oxide film) 5 is formed to a peripheral section 7 of the main surface and in a shape that is extended up to one part 8a of a peripheral flank 8 continuing to the peripheral section 7. Since a groove 12 is made up to the one part 8a of the peripheral flank by previously etching it at a prearranged location to be finally cut, the film 5 can be built up which being extended to the 8a part at the same time when forming the film 5 at a preceding stage making up the electrode 3.
